Cautions Correct piping work Wrong piping work
The refrigerant piping
should be the same level or
lower than connecting
position of piping to
outdoor units.
Piping work should be run
with side direction for
better uniform distribution
of refrigarant and oil like
next diagram.
Outdoor joint kits should
be installed in a horizontal
direction, even it is a low
pressure pipe.
When the piping length
between outdoor and
branch joints is 2m(6.6 ft)
or more, a vertical trap has
to be installed like right
diagram.
2m(6.6 ft) or over
Less than 1m(3.3 ft)
200~300mm
(7-3/4~11-3/4in)
2m(6.6 ft) or over
Horizontal length =
over 100mm(3-7/8in)
Minimum
